The faceted “gemstones” in these containers are captive, meaning that once printed they rotate freely within the wall.

This design is particularly suited to printing with multicolour filament as rotating the gemstones allows for visualization of the different filament colours.

This model features the tricolour “Silk Red & Yellow & Blue” filament by Eryone.

Once printed, allow the print to cool. Wiggle each gem back and forth until it breaks from the small internal supports. Twist it a few times until it turns smoothly.
